What is photography?
Photography is the art of capturing images using light. Images are captured by either taking pictures, video recording or motion picture film.
2. Camera Types
There are several types of cameras used in photography including SLR (single lens reflex), DSLR (digital single lens reflex) and mirrorless.
Exposure refers to how much light is allowed into the camera. The amount of light determines whether the image is overexposed or underexposed.
4. Light Meter
A light meter measures the amount of light entering the camera. A properly exposed photo should have a reading between 0 and 100. An exposure value (EV) number is assigned to each reading.
Flash is a device that emits light at a specific time to illuminate the subject. There are two types of flash devices: manual and automatic.
Filters are placed over the lens of the camera to change its color or effect the way it photographs. Different filters are used depending upon the desired look.
The lens is the only part of the camera body that touches the image sensor. It controls what part of the scene is focused and the focal length of the photograph.
You need equipment for almost everything you do and photography is no exception. At the absolute minimum, you’ll want at least two lenses (wide-angle and zoom) and a camera body. You may need even more depending on what type of images you plan to capture. If you’re just starting out, you don’t need anything fancy. A basic DSLR or interchangeable lens camera is fine.
2. Learn Basic Camera Functions
While the technical aspects of using a digital camera isn’t terribly complicated, knowing how to use its various features can make your experience much easier. Learning about these features can help you maximize your results while minimizing the amount of time you spend struggling with the basics. Once you get comfortable with the basics, you can move on to learning how to take creative control over your shots.
3. Learn About Exposure
Your camera’s exposure mode determines how sensitive the sensor is to light. In general, the lower the number, the less light you’ll need to expose properly. Your camera offers several different modes to choose from, including Program Mode, Shutter Priority Mode, Aperture Priority Mode, and Manual Mode.
Exposure Modes Explained
Program Mode – Uses pre-programmed settings based off of a certain metering area. These are great if you’re shooting a subject that doesn’t change brightness levels often.
Shutter Priority Mode – Allows you to set the shutter speed while automatically adjusting the aperture to achieve proper exposure. This gives you some flexibility to create unique exposures without having to worry about fiddling with the ISO setting.
Aperture Priority Mode – Lets you adjust both the shutter speed and aperture simultaneously, giving you complete control over depth of field.
Manual Mode – Allows you to manually select the exposure compensation value and aperture size. This is good for more advanced users who know exactly what they want their final image to look like.
4. Master Exposure Compensation
In addition to automatic exposure controls, you can also use Exposure Compensation to increase or decrease the exposure level. Adjusting Exposure Compensation lets you boost or dim the ambient light in your scene. It works by adding or subtracting a specific amount of exposure from the base exposure level. You can also use Exposure Compensation when shooting HDR scenes.
